Echiodon atopus Anderson, 2005 A single specimen of a previously undescribed pearlfish was taken just north of Inaccessible Island. At first identified as a rather northerly specimen of the widespread, austral Echiodon cryomargarites Markle, Williams & Olney, 1983, it differs from that species in its much higher precaudal vertebral and D30 counts, fewer anal-fin rays anterior to the dorsal-fin origin and fewer pectoral fin rays (Markle et al. 1983; Markle and Olney 1990; Anderson 2005). It appears closer to the single known specimen of E. neotes but differs in having no vexillum, more precaudal vertebrae, more dorsal rays anterior to vertebra 31 and possibly fewer pectoral rays. Counts: PCV 38; D30 46; A30 46; P 18; ARDO 7; DRAO 0; MAO 7; MDO 8; VAO 6; VDO 8. Head pores: mandibular 5; preopercular 2; infraorbital 8; supratemporal 2; supraorbital 5; lateral 3.
